Data and stimuli of the experiment: Pictorial Space Crafts: The Ames' Glass

There are various ways to evoke stereopsis without binocular disparities. Closing one eye, or looking through a synopter are well-known methods. Ames (1925) listed nine ways of generating this so-called `plastic effect', one of which involves a cylindrically curved lens placed in front of one eye. We investigated qualitative perceptual effects of this particular way of viewing artworks. A total of 38 participants viewed three digitally reproduced paintings. <br>Initially, they were asked to spontaneously report the perceptual effect of the lens. While being naive to the purpose of the experiment, 66% of the participants reported increased depth experience. In addition, participants reported increased contrast, color vibrance, and material expression (e.g. increased shininess). <br>During a second part of the experiment, we asked to report on seven qualities, Depth, Color, 3D shape, Realism, Detail, Light and Material. All qualities increased significantly except Detail, which seemed to show idiosyncratic results: the majority of the observers experienced a decrease of detail, while a minority reported, surprisingly, an increase of detail. <br>The data set contains the raw responses and also the data we used to perform analysis with Claude.ai including prompts.

存在多种无需双眼视差（binocular disparities）即可唤起立体视觉（stereopsis）的方法。闭上单眼，或通过同视器（synopter）观察，均为这类方法中广为人知的两种。埃姆斯（Ames）于1925年列举了9种可产生这种被称为‘可塑性效应（plastic effect）’的方法，其中一种是在单眼前放置圆柱曲面透镜（cylindrically curved lens）。本研究针对这种特定的艺术品观察方式所产生的质性知觉效应展开了探究，总计38名被试观看了3幅数字复刻画作。
起初，被试被要求自发报告该透镜带来的知觉效应。在对实验目的毫不知情的情况下，66%的被试报告称自身的深度感知体验有所增强。此外，被试还提及对比度、色彩鲜活度以及材质表现力（如光泽度提升）均有所提升。
实验的第二阶段，我们要求被试对7项知觉维度进行报告：深度、色彩、三维形状、真实感、细节度、光线与材质。除细节度外，其余各项维度的评分均出现显著提升；而细节度的结果则呈现出个体特异性：绝大多数被试报告细节感知有所下降，但令人意外的是，少数被试表示细节感知有所增强。
本数据集包含原始应答数据，以及我们用于结合Claude.ai开展分析所用的全部相关数据（含提示词）。
